OBJECTIVETo evaluate the operation method and prevention from complications of extracranial carotid stenosis.

METHODSThree cases of carotid angioplasty and stenting for 271 patients with extracranial carotid stenosis were performed from October 2001 to June 2008. Before the operation, take Clopidogrel for 75 mg/d, Aspirin Delayed-Release Capsules for 100 200 mg/d, Simvastatin for 40 mg 1/night, for 5 - 10 d. Then treat continuous vein infusion Heparin 50 mg/d for 2 d. After the operation, continue antiplatelet and reduce blood fat therapy.

RESULTSAll 300 carotid stenting were successfully accomplished. DSA showed that the diameter of stenosed segment of carotid artery was markedly enlarged, and all clinical ischemia signs were improved remarkably. Seven cases suffered from complications in one week after operation and one died. Following up 3 - 24 months in 226 patients, restenosis were found in 5 cases, among which 45 patients were evaluated at follow-up by means of ultrasonic examination for 36 months or so, no restenosis was found. No ischemic attack occurred at follow-up.

CONCLUSIONSThe satisfactory effect and safety are achieved in the therapy of carotid stenosis by carotid angioplasty and stenting. Correct intraoperative treatment and skilled techniques are the key points of success.
